Twenty minutes, keeps three days, and holds together in a lunchbox without going soggy. Dress the quinoa while it is still warm — that is when it takes in the flavour.

Quinoa is one of the few plant foods that is a complete protein on its own, which is the reason it earns its place over rice or pasta in a lunch like this.
Quinoa contains all nine essential amino acids, and it brings fibre, magnesium and iron with them. With the edamame and pumpkin seeds, the bowl reaches about 23g of plant protein — enough to hold appetite through the afternoon, which a pasta salad of the same size does not.
The combination is also why the blood-sugar response is gentle. Protein, fat and fibre arriving together slow how quickly the starch in the quinoa is absorbed, and that steadier curve matters beyond energy: repeated large insulin responses are closely linked to insulin resistance, which tracks with lower testosterone in men and with more difficult symptoms through perimenopause.
Pumpkin seeds are here for zinc and magnesium. Zinc holds an authorised claim for the maintenance of normal testosterone levels in the blood, and on a plant-based diet it is the mineral most likely to run short, because the phytates in grains and pulses reduce its absorption. Toasting the seeds improves the flavour; it does not meaningfully change the minerals.
Edamame are young soybeans, so they carry isoflavones — the plant compounds covered in more detail under phytoestrogens. What soy can realistically do for low oestrogen: how to increase oestrogen naturally.
It keeps three days in the fridge. Store the seeds separately.
